13 claims.

This invention relates to internal combustion engines and moreparticularly to engines of the Diesel type.

An object of this invention is to provide a novel and improved drivemechanism for a plurality of Diesel engine elements.

Another object of my invention is to provide a driving unit for aplurality of devices associated With an engine which can be readilyattached and detached from the crank case.

A further object of the invention is to provide a plural drive andhousing for elements cfa Diesel engine which can be utilized forapplication to either side of an engine so that two types of deviceswill not be required for use with engines disposed on two sides of aboat, for example, where it is desirable to have such mechanism onadjacent sides.

Other objects of the invention will appear from the followingdescription, taken in connection with the drawings, which form a part ofthis specification, and in which:

Fig. 1 is a top plan view of an engine with which the invention isassociated;

Fig. 2 is a side elevation of the same;

Fig. 3 is a vertical sectional View of the unitary driving mechanismtaken on line 3-3 of Fig. 4;

Fig. 4 is a horizontal sectional View of the unitary driving mechanismtaken on line 4 4 of Fig. 3;

Fig. 5 is another sectional view taken on line 5-5 of Fig. 3.

Referring now to the drawings by characters of reference, 10 indicatesthe crank case and 11 the bottom cover or pan of a Diesel type of inlineengine through which the conventional crank shaft extendslongitudinally. A multi-cylinder block 12 is secured upon the crankcase, and side cover plates 13 extend between4 the head cover 14 andthecrank case in spaced relation from the sides of the cylinder block.

- The crank case 15 at one end of the cylinder block is enlarged, andsecured to one wall thereof by the bolts 16 is a casing 17 forsupporting and .carrying the compressed air distributer, the fuel oilpump and the tachometer. The attached end l.of the casing is formed witha central bearing 18 while the opposite end of the casing has a lbearing19 detachably associated therewith. A drive shaft 20 having spacedhelical gears 21 fixed thereon is carried by the bearings in the casing,such shaft being removable endwise from the casing when the bearing 19is detached. The drive shaft extends into the crank case and is.provided with a gear 22 which is driven by gearing 1931. Serial No.509,674

(Cl. 1Z3--195) in the crank case (not shown) actuated by the crank shaftor some other rotating engine element.

The casing extends parallel with one side of the crank case and isformed with similar parallel top and bottom walls having alignedopenings 23 therein. The casing with the drive. shaft therein can beassembled with the crank case so that" either the top or bottom wall isuppermost, and therefore it can be applied equally well to either theright or left side of an engine. This arrangement is an advantage when apair of engines are employed and related so that the mechanisms mustbearranged on adjacent sides of engines, for example with a pair of boatengines where the apparatus is located on the inner sides thereof,because otherwise two casings of different form would be required.

A removable cap or plate 24 is secured over each of the openings 23 inthe under wall of the casing by bolts 25 and bearings 26 extendtherefrom into the interior of the casing. Removable cap members 27, 28and 29 are secured over the openings in the upper wall of the casing bybolts and are provided with hollow bearing portions 30 which extend intothe casing and align with the bearings 26. Stub shafts 31, 32 and 33 arecarried by the aligned bearings and extend exteriorly of the -ca-pmembers .27, -28 and 29, while a helical gear` 34 is xed upon each stubshaft in a relation to mesh with the gears 21 on the drive shaft.Screwed upon the cap 27 is a tachometer casing 35 and the shaft 31 isassociated to drive the revolution counting meohansim therein in theconventional manner.

A pump casing 36 is mounted upon the cap 28, and the stub shaft 32extends into the casing for driving a conventional gear pump (notshown). This pump is connected with a source of koil supply by theconduit 37 and to the manifolds 38 on each side of the cylinders by theconduit 39. The manifolds 38 have a common overflow conduit 40associated therewith for conducting excess fuel oil back to the sourceof Supply. Fuel injection devices 47 are associated with opposite sidesof each cylinder to project fuel charges into the combustion chambersand are connected with the manifolds 38.

The cap 29 forms one section of a compressed air distributing casing andassociated therewith to complete the casing is a housing 41. A conduit42 leads into the housing and is connected with a suitable source ofcompressed air (not shown) which can be admitted to the `distributerwhen the engine is being turned over for starting. The stub shaft 33extends into the distributer chamber and has fixed thereto a distributerplate 43 which is adapted to rotate just above a plurality of passages44 leading one to each cylinder through the conduits 45. The plate isformed with an opening 46 which rotates over the passage openings sothat compressed air charges will be released through the conduits to thecylinders in their ring order from the chamber into which the conduit 42leads.

The tachometer, pump and distributer devices are detachable from thecasing and can be assembled upon the caps 27, 28 and 29 andl attachedtherewith to either wall of the casing. The caps or closures 24 arearranged to be secured to either wall of the casing. The entire assemblyof the casing and the units detachably secured thereto can be detachedfrom the crank case by removal of the bolts 16, the conduits associatedwith the pump and distributer, and the electric wiring associated withthe tachometer.

The inner end of the distributer cap member 29 is formed with a flange50 so that oil will be collected therein, and passages 5l establishcommunication between the collected oil and the shaft 33. The shaft isformed with a spiral recess 52 which will move oil from the passagesalong the entire length of the shaft bearing 53. The bearings for theother stub shafts 31 and 32 can be lubricated in the same manner as thebearing 53 if desired.

It will be seen that the device described can be associated with eitherside of an engine through the rearrangement of the parts. The device,furthermore, is simple in design, pro- Vides a compact arrangement andis readily detachable as an entire unit from the crank case or assubunits from the casing.
